Anything that is outside in all winds and weather and has to work perfectly day after day needs an especially robust design. That’s why all our steel sectional garage doors are double-skinned and insulated. The degree of insulation is described by the door types. Simply choose between the alternatives, premium sectional door type iso 20 or the deluxe door type iso 45, with the highest insulation thickness and a wide range of optional extras.
All iso 20 and iso 45 door sections are manufactured from hot galvanized thin steel sheet and provided with a polyester-based pre-finished coat or, in the case of Golden Oak and Rosewood a durable foil finished coating. Angular frames, guide rails as well as all fitting parts on the garage door are also galvanised so that no rust can start to form. You will have many years of pleasure and satisfaction with your garage door
